Portland is no stranger to rain. It defines the city as much as Powell’s Books, coffee shops, and the eternal debate over whether we really need another apartment complex in the Pearl. But in February 1996, the rain wasn’t just an inconvenience—it was a crisis.
That winter had already been weird. December and January had dumped an absurd amount of snow and ice across the region, freezing roads, snapping tree limbs, and forcing everyone to rediscover the joys of tire chains. Then came February’s warm, relentless rain—melting that built-up snowpack fast and sending it, along with weeks of accumulated rainfall, straight into Portland’s rivers and creeks.
The Willamette River rose more than 28 feet, nearly overtopping the downtown seawall. Johnson Creek, infamous for its frequent flooding, spilled over and inundated entire neighborhoods. Landslides collapsed highways, cutting off key roads. In response, city officials scrambled to build emergency barriers, while the Oregon National Guard was deployed to assist in evacuations. Even President Bill Clinton visited Portland to assess the damage and discuss federal disaster aid.
Tina wasn’t thinking about floods when she left for work that morning. As a buyer for Fred Meyer, she spent her days managing inventory and placing orders. The rain had been coming down hard, but in a city where wet weather is constant, it didn’t seem like a reason to worry.
An hour later, she returned from lunch to find her store cut off—completely surrounded by floodwaters.
What had been a normal parking lot was now a lake. Employees were stranded inside, customers were rushing to evacuate, and nearby roads had become impassable. In less than an hour, the flood had transformed the landscape, isolating entire sections of the city.
Tina was lucky. She made it home before conditions worsened, but for thousands of others, the flood came too fast. Families were stranded, businesses were lost, and in the aftermath, Portland faced millions of dollars in damages.
That was 1996—one of the worst floods in Portland’s modern history. But while it may have seemed like a once-in-a-lifetime disaster, experts warn that the risks are only increasing.
Portlanders don’t often think about floods. We worry about drizzle that lasts for weeks, the ever-present risk of “The Big One,” and whether our favorite dive bar will be replaced by yet another boutique fitness studio. But when it comes to rising water levels? That usually feels like a problem for other places—somewhere with hurricanes, or at least fewer moss-covered rooftops.
But history has a way of reminding us otherwise. When floods do hit Portland, they don’t do it halfway. The 1996 Willamette Valley Flood nearly overtopped the downtown seawall. The 1964 Christmas Flood wiped out entire communities. And Vanport? That city disappeared in a matter of hours.
Now, scientists are warning that these “once-in-a-generation” floods might not be so rare anymore. Climate change is making storms stronger and more unpredictable. Urban development is paving over natural floodplains, leaving water with fewer places to go. And while Portland has flood control measures in place, they aren’t foolproof.
So, what does this mean for you? It means that waiting until floodwaters are at your doorstep is not a strategy. Preparation is.
This article will walk you through exactly what you need to know:
And because we know you already have enough on your plate, we’ve put together a Flood Readiness Checklist to make things easy. It’s practical, quick to go through, and—most importantly—could save you thousands of dollars in damage (or, at the very least, help you avoid that post-flood regret of “I really should have moved my couch upstairs”).
Portland doesn’t flood often—but when it does, the city doesn’t do it halfway. Over the years, some of the worst disasters in Oregon’s history have involved water overwhelming rivers, neighborhoods, and infrastructure. These weren’t just inconvenient storms or heavy rain; they were events that reshaped the city, displaced thousands, and left behind lasting scars.
In the spring of 1894, relentless rainfall and rapid snowmelt from the Cascades caused the Willamette River to crest at a record-breaking 33.5 feet. Portland, still a young and developing city, was completely unprepared for what followed.
Entire sections of downtown vanished underwater. Roughly 250 city blocks were submerged, shutting down businesses, rail lines, and public transit. People navigated the streets in rowboats, with floodwaters reaching the second stories of buildings along the waterfront.
Back then, flood control infrastructure was virtually nonexistent—there was no seawall, no dams upriver, and no real way to stop the water from taking over. The city essentially waited for the river to recede while scrambling to save what it could. When the waters finally withdrew, the damage was catastrophic, and it was clear that Portland needed better protections against future floods.
Vanport was Oregon’s second-largest city, home to more than 18,000 residents—many of them Black families who had moved to the area during World War II to work in the Kaiser Shipyards. Built in the floodplain between the Columbia River and the sloughs, the city was protected only by a system of berms and dikes. Officials insisted that these barriers would hold.
They didn’t.
On May 30, 1948—Memorial Day—the Columbia River, swollen from weeks of heavy rain and snowmelt, pushed through a railroad berm, sending a wall of water into Vanport. Within hours, the entire city was gone. Homes were ripped from their foundations, cars were swept away, and families had only minutes to escape.
Fifteen people died, and thousands more were left homeless. But the impact of the flood went beyond physical destruction. Vanport had been one of the most racially diverse communities in the Pacific Northwest, and its destruction exposed deep inequalities in Portland’s housing policies. Many displaced residents, particularly Black families, faced extreme difficulty finding permanent housing due to discriminatory real estate practices—a legacy that still influences the city today.
The Vanport disaster was a turning point. It led to major changes in flood control policies and the construction of additional dams, levees, and reservoirs throughout the Columbia River Basin. But it also served as a harsh reminder that in the Pacific Northwest, water always finds a way.
If the 1894 and Vanport floods were lessons in unpreparedness, the Christmas Flood of 1964 proved that even modern infrastructure wasn’t always enough.
December started with a series of bitterly cold storms that froze the region solid. Then, just before Christmas, an unseasonably warm atmospheric river arrived—dumping relentless rain and melting the deep mountain snowpack all at once. Rivers across Oregon and Washington surged to record levels.
In Portland, the Willamette River rose 12 feet above flood stage, submerging key roadways, sweeping away bridges, and forcing thousands to evacuate. The lower deck of the Steel Bridge disappeared beneath the rising water. Across the state, hundreds of homes, highways, and small towns were wiped out as the flood destroyed everything in its path.
The damage was staggering: More than $157 million (in 1964 dollars) in destruction, entire industries crippled, and a recovery process that stretched for years. The flood was so severe that it helped shape modern flood management across the state—leading to the creation of new dams, reservoirs, and flood-control infrastructure designed to keep the Willamette and Columbia Rivers in check.
But even those improvements weren’t enough to stop what came next.
By 1996, Portland had more flood protections than ever. The city had built levees, improved drainage systems, and reinforced major waterways. But nature had other plans.
That winter started with historic snowfall, ice storms, and bitter cold. When February arrived, an extended stretch of warm, relentless rain melted the snow almost overnight. With nowhere else to go, the water rushed into the rivers, which surged past their limits and into the city.
The Willamette River crested at 28.6 feet, coming dangerously close to overtopping downtown’s seawall. Volunteers and emergency workers scrambled to stack hundreds of thousands of sandbags along the waterfront to keep the river from breaking through. Across the metro area, roads disappeared under floodwaters, mudslides buried highways, and entire neighborhoods in low-lying areas were inundated.
Some of Portland’s most well-known landmarks were swallowed by the flood. The Oregon Zoo had to be partially evacuated as water rose near enclosures. The OMSI parking lot was completely underwater. The destruction wasn’t just limited to Portland—across Oregon and Southwest Washington, entire communities faced catastrophic damage.
The response was massive. President Bill Clinton visited Portland to assess the damage and promise federal aid, while the Oregon National Guard was deployed to assist with evacuations and emergency response.

In total, hundreds of homes were destroyed, thousands of people were displaced, and the financial toll ran into the hundreds of millions.
Every major flood in Portland’s history has been a wake-up call. After 1894, the city knew it needed better flood planning. After Vanport, it became clear that ignoring flood risks could have devastating human consequences. The 1964 flood pushed the state to improve its flood-control infrastructure, and 1996 showed that even with modern systems in place, nature could still overwhelm them.
The big question now: What comes next?
Because if history has taught Portland anything, it’s that another flood is always coming. The only question is when—and whether the city will be ready.
For decades, Oregon’s climate has been shaped by its famous Pacific Northwest rains—steady, persistent, but usually manageable. That balance, however, is shifting.
As global temperatures rise, the atmosphere holds more moisture. That means when storms do roll in, they’re dumping more rain in shorter periods of time. The slow, misty drizzles that Portlanders know so well are increasingly being replaced by intense downpours—the kind that overwhelm storm drains, swell rivers to dangerous levels, and turn streets into waterways in a matter of hours.
These aren’t just hypotheticals. Heavy rainfall events in Oregon have already increased by 10% since 1950, and projections suggest that trend will accelerate. More water in the air means more frequent, more intense floods.
Meanwhile, higher temperatures are also melting mountain snowpacks earlier in the season. The steady, gradual melt that once fed Oregon’s rivers in a controlled way is becoming more erratic, sometimes sending large amounts of runoff into the Willamette and Columbia Rivers all at once—raising flood risks even before the spring rains arrive.
And then there’s the wildcard: atmospheric rivers. These long, narrow bands of moisture can deliver staggering amounts of rainfall in just a few days—as seen in the deadly 1964 and 1996 floods. As climate change intensifies, atmospheric rivers are becoming stronger and more frequent, increasing the chances of another major flood event in Portland.
It’s not just a matter of bigger storms. Even on an average year, Portland is expected to get wetter.
For a city that already struggles with drainage issues and urban flooding, that’s a problem. More intense rain events mean stormwater systems will be overwhelmed more often, leading to flash floods, urban street flooding, and increased risks of landslides.
But the biggest long-term threat? The rising Columbia River.
As sea levels rise globally, Portland—despite being 100 miles inland—isn’t immune. By 2100, the Columbia River’s sea level may rise by at least 3 feet. That might not sound dramatic, but for low-lying areas like Sauvie Island, the Columbia Slough, and neighborhoods along the North Portland Harbor, even a modest rise could lead to permanent inundation of some land and much higher flood risks.
A 6-foot rise—also within the realm of possibility—would put large sections of Portland’s industrial areas, bridges, and riverfront neighborhoods at risk.
For a city built around its rivers, that’s a future that demands planning—and action.
Floods aren’t like earthquakes. They don’t strike out of nowhere, without warning, in the middle of your morning coffee run. But that doesn’t mean you’ll always have plenty of time to react, either. Some floods develop slowly over days, giving residents time to evacuate and protect their property. Others arrive so quickly that by the time you realize what’s happening, you’re already in knee-deep water.
Understanding the different types of floods and the amount of warning they provide can mean the difference between calmly securing your home or scrambling to grab valuables as water pours through your front door.
River floods and flash floods behave very differently, both in terms of how they form and how much time you have to respond.
River floods, caused by prolonged rainfall or rapid snowmelt, develop gradually over hours or even days. This slow buildup provides some warning, allowing local agencies to monitor water levels and issue alerts. During the 1996 Willamette Valley Flood, Portland had about a day's notice before the river reached dangerous levels. While that may sound like enough time to prepare, the Willamette ultimately crested at 28.6 feet—coming alarmingly close to breaching the downtown seawall. For homeowners in flood-prone areas, this kind of lead time is valuable, but only if action is taken immediately. Typically, river floods offer a 6 to 24-hour window to prepare before significant inundation occurs.
Flash floods, on the other hand, don’t wait. They form suddenly due to heavy localized rainfall, overflowing storm drains, or, in extreme cases, dam failures. Unlike river floods, which announce themselves gradually, flash floods arrive without warning and escalate within minutes. If the conditions align—a powerful storm, an overburdened drainage system, or steep terrain directing water downhill—streets can turn into rushing rivers before emergency alerts are even sent out. These floods are particularly dangerous because of how fast they move and how little time they give people to escape. The lead time for flash floods ranges from zero to six hours, with some occurring so suddenly that no official warning is issued at all.
For Portland residents, both types of flooding present serious risks, but flash floods are often underestimated. If you live in a low-lying area, near a creek (like Johnson Creek, which floods frequently), or in a neighborhood prone to poor drainage, heavy storms should never be ignored. If water starts rising rapidly, don't wait for an alert—get to higher ground immediately.
Floods don’t operate on your schedule. They don’t care if you’re in the middle of cooking dinner or commuting home from work. That’s why staying ahead of alerts and warnings is crucial—because by the time you see floodwaters in your driveway, it’s already too late to prepare.
The National Weather Service (NWS) provides flood alerts in stages, and knowing what they mean can make all the difference.
The NWS issues flood alerts in stages, but knowing what they mean can make all the difference.
If you take one thing away from this: A "watch" means prepare. A "warning" means act.
In addition to NWS alerts, several emergency notification systems provide real-time updates. Flood alerts won’t help you if you never receive them. Here’s how to make sure you’re always in the loop.
The key to flood safety is preparation, not reaction. Whether you have 24 hours or just six minutes, acting before the water arrives is the only way to stay ahead of the disaster. River floods give you time—use it wisely. Flash floods do not—stay alert. And most importantly, don’t wait until you see water creeping up your street to start preparing. By then, your options are already limited.
Floods don’t arrive all at once. The rain starts falling harder. The creeks start running faster. Then, the alerts start rolling in. Flood Watch. Flood Warning. Flash Flood Warning. By the time you see water pooling in your street, you’re already losing valuable time.
This is when every decision matters. Do you stay? Do you go? What should you be doing in the next five minutes, hour, or day to ensure you’re not caught off guard? The biggest mistake most people make isn’t underestimating the flood—it’s waiting too long to act.
When a flood warning is issued, the first question is whether you need to get out immediately or hunker down and wait it out.
If local officials issue an evacuation order, do not ignore it. These decisions aren’t made lightly—they’re based on real-time water level data and historical flood patterns. Staying behind when you’re told to leave isn’t just risky—it can put first responders in danger if they have to rescue you later. Leave as soon as possible, before floodwaters make the roads impassable. Follow designated evacuation routes, avoid shortcuts (which may be underwater), and never assume you can outrun rising water.
Before you leave, grab your emergency go-bag. This should include important documents (insurance papers, IDs), medications, a flashlight, bottled water, non-perishable food, extra clothes, and anything else you may need if you’re away from home for days. If you have pets, bring their essentials, too.
If no evacuation order is given, that doesn’t mean you’re in the clear. It means authorities believe you’re safer staying put—but only if you take the right precautions. Assess your surroundings. Is your home in a low-lying area? Do you have a basement that could flood? Are roads leading out of your neighborhood already filling with water? If there’s any doubt about whether you’ll be trapped if conditions worsen, leave before it’s too late.
If you do shelter in place, prepare as if you could be stranded for several days. Make sure you have drinking water (at least one gallon per person per day), food, flashlights, batteries, and a way to communicate in case power and cell service go out. Most importantly, know your escape routes in case things take a turn for the worse.
If you have only minutes before floodwaters reach your home, you won’t have time for everything. Prioritize the actions that will protect your safety first.
Floodwaters don’t just ruin carpets—they destroy everything they touch. Electronics, furniture, family heirlooms, important documents—all at risk. If you have time before the worst of the flooding begins, move valuable items to higher floors or at least onto countertops and shelves to keep them out of reach.
Outside, secure anything that could turn into a floating hazard. Lawn furniture, trash bins, bicycles—anything not anchored down can become a projectile in strong currents. Move them inside or tie them down.
One of the biggest dangers during a flood isn’t just the water—it’s what’s inside the water. Gas leaks, live electrical wires, and contaminated sewage all pose deadly risks.
If flooding seems imminent, turn off your home’s gas, electricity, and water—only if you can do so safely. Unplug appliances to prevent electrical fires. If water is already rising inside your home, do not attempt to touch electrical panels or outlets—water conducts electricity, and you could be electrocuted.
Floodwater is not just water. It’s a mix of sewage, chemicals, debris, and bacteria that can cause serious infections if it gets into cuts or eyes. If you absolutely must wade through water, wear protective clothing, waterproof boots, and gloves.
Never assume that standing water is safe. It may be hiding sinkholes, sharp debris, or downed power lines. Just a few inches of fast-moving water can knock you off your feet, and if the current is strong, even a foot of water can sweep away a car.
If you need to evacuate by car, do not attempt to drive through flooded roads. It takes just six inches of water to cause a car to stall and one foot to sweep a vehicle away. Water can also conceal road damage—what looks like a shallow pool could actually be a washed-out street.
If you’re on foot, head for higher ground. Never try to cross fast-moving water—it’s stronger than it looks. If you are caught in a flood and need immediate help, call 911 and get to the highest, safest point possible.
For a city famous for its rain, Portlanders don’t spend much time thinking about floods—at least, not until they’re ankle-deep in water wondering whether their car insurance covers “unexpected street-turned-river” incidents. But flood risk in Portland isn’t uniform; some neighborhoods are significantly more vulnerable than others. And as climate change reshapes the Pacific Northwest’s weather patterns, those risks are only increasing.
Floods in Portland aren’t just a matter of how much rain falls—it’s about where that water has nowhere to go. The city’s rivers, creeks, and low-lying areas create natural flood pathways, and urban development, with its endless concrete and impervious surfaces, only makes the situation worse. While flood control measures like levees, reservoirs, and drainage improvements have helped, certain neighborhoods remain at high risk of significant flooding events.
Not all parts of Portland face the same level of danger when it comes to flooding. If your home or business is located near the Willamette or Columbia Rivers, in a floodplain, or in a historically flood-prone neighborhood, your risk is substantially higher.
Some of Portland’s most scenic waterfront areas also happen to be some of its most vulnerable.
The East Columbia and Bridgeton neighborhoods sit right along the Columbia River, meaning they are one major storm or rapid snowmelt away from significant flooding.
Levees and flood barriers provide some protection, but as seen in past flood events, those measures are not infallible. The Columbia is a powerful river, and when it surges, low-lying communities are the first to take the hit.
Further south, the Pearl District and parts of downtown Portland also face flood risks from the Willamette River. While the downtown seawall has kept Portland’s core from experiencing catastrophic flood damage, it’s not an impenetrable barrier. If water levels rise fast enough—like they nearly did in 1996—the heart of the city could see severe flooding. Additionally, rapid urban development has increased impervious surfaces, making it more difficult for stormwater to drain effectively, which raises the risk of flash flooding in heavy rain events.
If you live near Johnson Creek, you already know the drill.
Neighborhoods like Lents and Powellhurst-Gilbert have been battling flooding for decades. Johnson Creek is infamous for overflowing its banks, often turning backyards into lakes and roads into temporary rivers. Efforts like the Johnson Creek Restoration Plan have helped reduce some of the worst flooding events by restoring natural floodplains and wetlands, but the risk remains high—especially during prolonged rainstorms.
Unlike the Willamette or Columbia, which rise gradually during large flood events, Johnson Creek can spill over with little warning, particularly after heavy rainfall. For homeowners in this area, flood insurance isn’t just a precaution—it’s a necessity.
Some of the most geographically vulnerable areas aren’t in Portland’s central neighborhoods, but in North Portland and across the river in Vancouver.
Areas near Vancouver Lake and the Columbia River face serious flood risks, particularly as climate change increases storm intensity and sea levels rise. These low-lying regions are already highly susceptible to flooding, and when water levels surge, both transportation networks and housing infrastructure are at risk.
North Portland, including areas along the Columbia Slough, faces a similar problem.
While this part of the city isn’t as frequently discussed in flood preparedness conversations, the reality is that neighborhoods along the North Portland Harbor Channel and industrial areas near the river are just as exposed as the Columbia-facing communities further east.
The challenge in all of these areas isn’t just flood damage—it’s accessibility. Flooding here could mean major transportation routes like I-5 and key freight corridors are underwater, further complicating evacuation and emergency response efforts.
Portland has already seen major floods reshape its landscape. But with climate change driving more extreme weather events, the risks are shifting—and in some areas, getting worse.
Currently, about 35,000 properties in Portland are at risk of flooding within the next 30 years, according to projections by First Street Foundation. That equates to 15.5% of the city’s properties sitting in designated flood zones—a number that is expected to increase slightly as new floodplain models are developed.
The closer a home is to a river, creek, or low-lying floodplain, the more likely it is to experience flooding. However, as seen in other flood-prone cities, areas outside of traditional flood zones are also starting to see an uptick in risk due to urbanization and shifting storm patterns.
It’s not just about heavy rain—Portland’s flood risk is being influenced by multiple factors at once.
The biggest wildcard in Portland’s flood future? Sea level rise and intensifying storms.
More frequent downpours mean storm drains will be overwhelmed more often, increasing the likelihood of flash floods even in places that historically haven’t flooded.
Recognizing this growing risk, the City of Portland has implemented the Floodplain Resilience Plan, a long-term effort to update zoning laws, strengthen environmental protections, and improve floodplain management. The goal is twofold:
The plan includes stricter development regulations in flood-prone areas, expanded requirements for flood-resistant construction, and new efforts to restore natural floodplains to help absorb excess water.
While these measures will help, they won’t eliminate the risk entirely. For homeowners, renters, and business owners in flood-prone neighborhoods, the best protection remains preparation. Understanding your flood risk isn’t just about knowing whether your home is in a floodplain—it’s about being ready before the next major storm hits.
No one likes to think about insurance—until they need it. And when it comes to flooding, most people don’t realize they need it until it’s too late.
In Portland, where the rivers run high, the creeks overflow, and the city’s drainage system is often one atmospheric river away from a bad day, flood insurance is something more homeowners, renters, and business owners should be considering.
Here’s the harsh reality: standard homeowners insurance does not cover flood damage. It doesn’t matter if your basement turns into a swimming pool or if your ground-floor apartment is suddenly at the bottom of an unplanned lake—without flood insurance, you’re on your own.
So, who actually needs it? And how does it work? Let’s break it down.
You might assume flood insurance is only necessary for people who live right on the riverfront, but water has a way of finding places to go—often where you don’t want it.
If your home is near the Willamette River, Columbia River, or Johnson Creek, your flood risk is significantly higher than the rest of the city. Properties in these areas have a long history of flooding, and as climate change increases storm intensity, those risks aren’t going away.
If you have a mortgage on a home in a designated FEMA flood zone, flood insurance isn’t optional—it’s required. Lenders don’t take chances when it comes to properties that could be underwater (literally), and if you’re financing a home in one of these areas, you’ll need to factor in the cost of coverage.
Even if you’re not in a high-risk area, that doesn’t mean you’re in the clear. In fact, 25% of all flood insurance claims come from properties outside of FEMA-designated flood zones.
Why? Because floods don’t respect government maps. Urban flooding from storm surges, clogged drainage systems, or sudden heavy rainfall can damage homes far beyond official floodplains.
Portland’s hilly terrain and network of creeks mean some neighborhoods are more vulnerable than people realize. A house at the bottom of a slope? That’s a flood risk. A home with poor drainage? That’s a flood risk. A basement in Portland? Definitely a flood risk.
If you rent, your landlord is responsible for the building—but not your stuff. That means if a flood wipes out your furniture, electronics, or anything else in your apartment, your landlord’s insurance won’t cover it.
Renters can purchase contents-only flood insurance to protect their belongings. And considering how quickly the cost of replacing clothes, electronics, and furniture adds up, it’s worth considering.
For business owners, flooding is more than just a property concern—it’s a financial one. If a flood damages inventory, equipment, or the building itself, it could shut down operations for weeks. Standard business insurance won’t cover flood damage, so if your business is in a flood-prone area, getting the right coverage could mean the difference between recovering quickly or shutting down permanently.
Not all flood insurance is created equal. The two main options for coverage are the National Flood Insurance Program (NFIP), backed by FEMA, and private flood insurance, which offers alternative or additional coverage.
The NFIP was created to help homeowners, renters, and businesses access affordable flood insurance in high-risk areas.
It’s available in participating communities (Portland included) and provides government-backed coverage.
A few things to know about NFIP policies:
For homeowners in moderate to high-risk areas, NFIP is often the easiest and most affordable way to get flood insurance. But if you own a high-value home or need coverage beyond NFIP’s limits, private insurance might be a better option.
Private insurers have entered the flood insurance market in recent years, offering more flexible coverage options than NFIP.
What makes private insurance different?
Private flood insurance can sometimes be cheaper than NFIP, especially for homeowners outside of high-risk zones. But because private insurers can drop policies or adjust rates based on risk, NFIP is often considered the more stable long-term option.
Floods don’t wait for you to be ready. They don’t care if you were planning to fix that crack in your foundation “next weekend” or if your basement is still full of holiday decorations and old furniture. When the water comes, it moves fast—and whatever’s in its way pays the price.
But while you can’t stop a flood from happening, you can control how much damage it does to your home. Taking the right precautions now can mean the difference between minor repairs and a catastrophic loss. Here’s how to flood-proof your home before the next big storm arrives.
Your home’s foundation is the first line of defense against rising water—and it’s also one of the most vulnerable parts of your house. If water finds its way in through cracks, unsealed walls, or porous materials, it doesn’t just sit there. It seeps. It spreads. It weakens everything it touches.
To keep water out:

This is the kind of preparation you want to do before flood season hits. Because once water is already seeping through your basement, it’s too late to start patching cracks.
If you have a basement in Portland, you already know it’s a flood risk. It doesn’t take a major storm to turn an unprepared basement into a soggy, mold-prone mess.
That’s where sump pumps come in. These small but powerful devices remove water that seeps into basements before it has a chance to cause damage. When installed properly, they automatically pump out excess water, preventing flooding before it becomes a problem.
For extra security, consider a sump pump with a battery backup. Portland’s storms often come with power outages, and the last thing you want is for your pump to stop working when you need it most.
Just as important as keeping water out is making sure it doesn’t come back up through your drains. A heavy storm can overwhelm the city’s sewer system, sending contaminated water backing up through toilets, sinks, and floor drains. It’s exactly as disgusting as it sounds—and incredibly expensive to clean up.
To prevent this, install backflow valves on your sewer lines. These simple devices allow wastewater to flow out but not back in, meaning that when the streets are flooded, your home won’t be the one dealing with raw sewage in the basement.
If water reaches your electrical system, you have much bigger problems than a flooded basement. Electrical fires, short circuits, and permanent damage to expensive appliances can turn a bad situation into a nightmare.
To minimize damage:
Flooding isn’t just about water—it’s about what the water damages. Taking steps now to protect your home’s foundation, electrical system, and drainage will save you thousands of dollars in repairs and prevent long-term structural issues.
When a flood is coming, seconds matter. You won’t have time to dig through your closet for a flashlight or print out insurance documents while water is creeping up your front steps.
Preparation isn’t just about making things easier—it’s about making sure you can get out safely and recover faster.
Think of a go-bag as your portable survival kit—something you can grab at a moment’s notice if you need to evacuate. The goal is to have everything you need for at least 72 hours if you’re displaced from your home.
A well-packed go-bag should include:
If you have pets, don’t forget their needs. Food, water, leashes, carriers, and any medications should also be included.
Your go-bag should be somewhere accessible—not buried in a storage bin in the garage. The last thing you want to do when the water is rising is frantically search for supplies.
When a flood hits, everyone in your household should know what to do and where to go. Evacuation is chaotic enough—having a clear plan in place can make all the difference.
Start by identifying evacuation routes and safe meeting spots. If you need to leave, where will you go? If family members are separated, where will you reunite? Make sure everyone knows the plan before the flood warning comes.
Just as important as knowing where to go is knowing what to take. Secure important documents (home insurance, medical records, passports) in a waterproof container or digital cloud storage so they aren’t lost if your home is damaged.
If evacuation isn’t necessary but water levels are rising, move valuables, electronics, and irreplaceable items to higher ground. A few feet can mean the difference between saving and losing something important.
Flood planning isn’t just about physical preparation—it’s also about communication. Make sure every member of your household has a way to stay informed, whether through emergency alerts, NOAA weather radio, or text updates from local agencies.
Water and electricity do not mix. Neither do gas leaks and rising floodwaters. Before flooding starts, make sure you know how to safely shut off your home’s utilities.
If conditions are already dangerous, do not attempt to turn off utilities yourself. Evacuate immediately and let professionals handle it when it’s safe.
The floodwaters have finally receded. The streets are no longer rivers, the rain has stopped pounding against your windows, and emergency alerts have shifted from urgent warnings to cleanup instructions. But before you step back inside your home, take a breath—this is the most dangerous part of the disaster.
Flood damage isn’t just about wet floors and waterlogged furniture. It’s about structural instability, electrical hazards, and contaminated water that can make your home unsafe. Entering too soon—or without proper precautions—can turn an already devastating situation into something far worse.
Before you even think about walking through the front door, assess the damage from a safe distance. Floodwaters can weaken a home’s foundation, compromise its structural integrity, and turn your living room into an electrical death trap if water has reached outlets or wiring.
Floodwaters don’t just soak a house—they can shift it. Before stepping inside, do a thorough visual inspection of the exterior. Look for cracks in the foundation, leaning walls, or any visible signs of shifting. If the structure appears warped or unstable, do not enter.
Even if the exterior looks intact, proceed with caution. Warped floors, sagging ceilings, and doors or windows that no longer open properly could indicate hidden structural damage. Floods can weaken load-bearing walls and flooring, making collapse a real possibility. If something feels off, get an inspection before stepping inside. No possession is worth risking your life.
If there’s a strong smell of gas or a distinct hissing sound, evacuate immediately and call the utility company. Gas leaks are a serious hazard after floods, and even a small spark could ignite an explosion.
Even if the floodwaters are gone, hidden dangers remain. Electrical wires that have been submerged can stay live, gas lines can leak, and contaminated water can corrode pipes and lead to plumbing failures.
Before entering, shut off the electricity at the main breaker. If water has reached the breaker box, do not attempt to turn it off yourself—call an electrician. Gas should also be turned off at the main valve, and if it wasn’t shut off before the flood, a professional should inspect it before you attempt to restore service. Water lines should be turned off as well to prevent contamination from backflow into your plumbing system. If there’s any uncertainty about the safety of these systems, do not risk it. Call in professionals to assess and restore utilities safely.
Floodwaters don’t just bring mud and debris—they bring sewage, chemicals, and bacteria that turn your home into a biohazard zone. Anything that came into contact with floodwater should be treated as contaminated.

Standing water left behind by a flood is more than just an inconvenience—it’s a breeding ground for bacteria, mold, and hazardous waste. Sewage backups, industrial runoff, and chemical spills often mix into floodwaters, making exposure a serious health risk. Wear protective gear before handling any flood-damaged materials. Waterproof boots, gloves, and a mask are essential to protect yourself from pathogens, mold spores, and toxic residue.
If your home was submerged in deep floodwaters or near an area with industrial or sewage runoff, consider hiring a professional flood restoration team to handle cleanup safely. Mold can start growing within 24-48 hours of water exposure, so drying out your home quickly is critical. Ventilate the space by opening windows and using fans and dehumidifiers to reduce moisture.
Your instinct may be to rush in and start cleaning up, but taking the right precautions now can prevent injuries, illness, and further damage to your home. Do not enter a home with visible structural damage or signs of gas leaks, and always shut off all utilities before stepping inside. Treat all floodwater as hazardous, wear protective gear, and avoid direct contact whenever possible.
Recovery starts with safety. If in doubt, get professional help such as Droplet Restoration before going in. The flood may be over, but the danger isn’t gone yet. Let Droplet Restoration handle the heavy lifting. From assessing structural integrity to safely drying out and restoring your space, our storm recovery specialists are equipped to get your home back to normal, fast.
Flood damage doesn’t end when the water recedes. In fact, one of the biggest post-flood threats is what happens next: mold. If your home isn’t dried out quickly, moisture can settle into walls, floors, and hidden spaces, creating the perfect environment for mold to thrive. And once mold takes hold, it spreads fast—turning a water damage issue into a full-blown health hazard.
Acting immediately to dry out your home can prevent costly repairs, structural damage, and potential respiratory issues. Here’s how to stop mold before it starts.
The longer water sits, the worse the damage gets. Start removing standing water as soon as it’s safe to do so. If there’s a significant amount, use pumps, wet/dry vacuums, and industrial fans to extract water and speed up the drying process. Smaller pools of water can be soaked up with towels and mops, but the key is to keep air moving.
Open windows and doors to improve ventilation and reduce moisture buildup. The more air circulation you can create, the faster your home will dry out. If it’s humid outside, use fans and dehumidifiers indoors to help pull moisture from the air. Every hour counts—mold can start growing in as little as 24-48 hours.
Not everything can be saved. Porous materials like carpets, drywall, and insulation act like sponges, soaking up water and creating the perfect conditions for mold growth. If these materials are saturated, they need to go.
Furniture, clothing, and other salvageable items should be cleaned and dried within 48 hours. Move anything damp into a well-ventilated area with plenty of airflow. If an item still smells musty after drying, mold is likely already growing on it. When in doubt, throw it out—it’s not worth the risk of mold spreading to the rest of your home.
Even after visible water is gone, moisture lingers in walls, floors, and hard-to-reach spaces. A high-powered dehumidifier can help pull hidden moisture from the air, preventing condensation from settling into drywall or wood.
For extra protection, apply anti-mold solutions to damp areas. A mix of water and white vinegar or commercial mold inhibitors can help prevent mold spores from taking hold. Pay close attention to baseboards, crawl spaces, and any area that was submerged—these are common problem spots where mold thrives.
If mold has already started growing or if you’re dealing with severe water damage, professional help is the safest option. Companies like us, Droplet Restoration, specialize in storm recovery and mold prevention, ensuring that your home is properly dried, treated, and restored before long-term damage sets in.
Once the floodwaters are gone, the chaos isn’t over—you’re left with a damaged home, a mess to clean up, and the looming question of where to even start. Every decision you make in the first 24–48 hours can impact how quickly your home is restored, how much of the damage is covered by insurance, and whether you end up with lingering issues like mold or structural instability.
So, who do you call first? Your instinct might be to immediately start tearing out wet carpet or calling every contractor in town, but jumping ahead in the process can actually work against you. The first step is always insurance.
Before you touch a thing, document everything. Take clear photos and videos of all damage, including standing water, soaked furniture, damaged walls, and any structural issues. The more detailed your documentation, the easier it will be to file a flood damage claim.
Once you’ve collected evidence, call your insurance company and start the claims process immediately. Flood insurance—whether through **the National Flood Insurance Program (NFIP) or a private provider—typically requires fast reporting. The sooner you file, the sooner an adjuster can assess the damage and get you on the path to reimbursement.
Important: Do not start major repairs before an insurance adjuster has inspected the damage. If you remove materials or throw out damaged belongings before documenting them, you may lose out on coverage.
Once your claim is in motion, the next step is to bring in professionals who specialize in flood recovery. Restoration companies like Droplet Restoration are trained to handle water extraction, structural drying, and mold prevention—all critical to making sure your home doesn’t suffer long-term damage.
Unlike general contractors, water damage restoration specialists have the right equipment to detect moisture in walls, floors, and hidden spaces. They can remove standing water, dry out your home safely, and prevent mold growth before it starts. Mold remediation, in particular, is something you don’t want to tackle alone. Once mold starts spreading, it becomes a much bigger—and much more expensive—problem.
A professional restoration team can also work directly with your insurance company, helping to document damage properly and ensure you get the full coverage you’re entitled to.
Unfortunately, disaster zones attract scammers. After a major flood, it’s common to see "contractors" going door to door offering quick, cheap repairs. Many of these are unlicensed, uninsured, and unqualified, leaving homeowners with unfinished work, unsafe repairs, or outright fraud.
Before hiring anyone to handle flood damage repairs:
Flood recovery is overwhelming, but the right order of operations can make all the difference. Call your insurer first, bring in certified restoration experts next, and stay cautious about who you trust with repairs. Cutting corners in this phase can lead to bigger headaches down the road.
Homeowners aren’t the only ones who need to worry about flooding. Renters face just as much risk—sometimes more—because they often assume their landlord’s insurance will cover everything. Spoiler: It doesn’t.
Floods don’t discriminate between homeowners and renters, and if water starts pouring into your apartment, your lease agreement isn’t going to stop it. Understanding what’s at stake, what’s covered, and what you need to do before the water rises can save you thousands of dollars—and a major headache.
Absolutely. And if you rent in Portland, you might be at higher risk than you think. Many of the city’s rental properties—especially older buildings—aren’t designed to withstand major flooding. Add in unpredictable storm drains, low-lying areas, and the occasional century-old basement apartment, and you’ve got a recipe for trouble.
One of the biggest misconceptions renters have is that their landlord’s insurance will cover everything. It won’t.
If a flood damages the building itself—walls, floors, pipes, or electrical systems—that’s on the landlord’s policy. But everything inside your unit? Your furniture, your electronics, your clothes, your personal items—that’s on you. If you don’t have renters insurance that specifically covers floods, you could be left replacing everything out of pocket.
Beyond property damage, floods can force evacuations that leave tenants suddenly without a place to live. If floodwaters make your unit uninhabitable, where will you go? Some renters insurance policies include coverage for temporary housing, but only if flood insurance is part of your plan. Without it, you’re on your own.
Living in a ground-floor unit, basement apartment, or low-lying area? Your flood risk is significantly higher.
Apartment complexes in flood zones—especially those near Johnson Creek, the Willamette River, or older neighborhoods with poor drainage—are at an increased risk of flooding. During heavy rains, stormwater can pool quickly, overwhelming drainage systems and sending water straight into lower-level units.
If you’re unsure whether your building is in a flood-prone area, check the FEMA flood maps or ask your landlord. But even if your apartment isn’t technically in a floodplain, urban flooding can still happen—especially in areas with aging drainage infrastructure.
If you’re a renter in Portland, you might assume that your standard renters insurance has you covered in case of flooding. It doesn’t. And finding that out after your belongings are floating in two feet of water is the worst possible way to learn this lesson.
Most renters insurance policies cover certain types of water damage—like burst pipes or an overflowing bathtub—but they do NOT cover flooding caused by heavy rain, overflowing rivers, or urban drainage failures. That means if a storm floods your apartment, your insurance company isn’t going to help unless you have separate flood insurance.
A standard renters policy will typically pay for damage caused by internal water issues—like a burst pipe, a leaking washing machine, or a sudden plumbing failure. But the moment that water comes from outside your apartment—rising floodwaters, storm surges, or overflowing drains—it’s not covered.
This is a critical distinction, and one that catches renters off guard all the time. If your apartment floods because your upstairs neighbor’s toilet exploded, you’re in luck. If it floods because Johnson Creek decided to reclaim your living room? That’s on you.
If you live in a flood-prone area—or just don’t want to take the risk—you can purchase flood insurance for renters through the National Flood Insurance Program (NFIP) or private insurers. These policies specifically cover damage caused by flooding and can help replace your belongings if disaster strikes.
A flood insurance policy for renters typically covers:
What’s not covered? Your actual apartment. Your landlord is responsible for repairing structural damage to the building, but without renters flood insurance, you’ll be paying out of pocket to replace everything you own.
If you’re a renter in Portland, flood insurance isn’t just for homeowners. While your landlord’s policy covers the building itself, it does nothing for your belongings, temporary housing, or any costs you’ll rack up replacing everything you lost. That’s where additional flood insurance comes in.
Luckily, renters do have options—whether through the National Flood Insurance Program (NFIP) or private insurers. And considering flood recovery costs can easily hit thousands of dollars, an extra policy could be the difference between bouncing back or starting from scratch.
The National Flood Insurance Program (NFIP), managed by FEMA, offers flood insurance specifically for renters. Unlike homeowners' policies, which cover both the building and its contents, renters can purchase a contents-only policy—meaning it protects your furniture, electronics, appliances, clothing, and personal property if floodwaters reach your unit.
NFIP policies start at around $99 per year, depending on your location and flood risk. While it won’t cover temporary housing costs if you have to evacuate, it’s a solid baseline to ensure you’re not paying out of pocket to replace everything.
One important detail: NFIP coverage has a 30-day waiting period. That means you can’t buy a policy right before a storm and expect coverage to kick in. The best time to get flood insurance is before you need it.
While NFIP provides government-backed coverage, private flood insurance has emerged as a competitive alternative. Some renters opt for private policies because they offer:
Private flood insurance can be more flexible and tailored to your needs, but costs vary based on location and risk level. If you’re renting in a high-risk area or simply want more comprehensive protection, comparing NFIP and private insurance is worth the time.
Portland’s relationship with water is complicated. For most of the year, it’s a steady drizzle, a moody mist, or—on particularly wild days—a heavy downpour that sends everyone running for cover under the nearest coffee shop awning. But as history has made abundantly clear, Portland’s rivers, creeks, and storm drains don’t always play nice. When a flood hits, it doesn’t politely knock—it barges in, takes over your basement, and leaves you with a soaked couch and a massive headache.
And yet, so many Portlanders are still unprepared. Maybe it’s because we’re more worried about “The Big One” than a flood. Maybe it’s because the city’s biggest disasters happened decades ago, making them feel like ancient history rather than a real, ongoing risk. But the truth is, flooding isn’t a distant possibility—it’s a recurring reality, and it’s only getting worse.
So, let’s make this simple:
Flooding may not be Portland’s everyday problem, but when it does happen, it happens fast—and the people who are ready always fare better than the ones who aren’t. The choice is yours: Wait and hope for the best, or prepare now and know you’ll be ready when the water starts to rise.
If there’s one thing Portlanders love, it’s preparation. We stockpile emergency earthquake kits, carry tire chains nine months out of the year "just in case," and wouldn’t dream of heading out for a hike without a waterproof jacket—even if the forecast swears it’ll be sunny. But when it comes to flood preparedness, too many people assume they’ll just “figure it out” when the time comes.
That mindset? It’s exactly how you end up wading through knee-deep water in your living room, wondering why you didn’t take this more seriously.
Preparation isn’t complicated, and it doesn’t have to be overwhelming. In fact, it comes down to a few simple steps that can make a massive difference when the next big flood hits:
Flood preparedness isn’t about paranoia—it’s about being smart.
